This recipe needs to bring out the distinction with Choice (#33, #34), Foldouts (#35), and multiple images that are all part of a scene.

Whereas the flap open/flap closed images of #33 are a Choice, the multiple media of Fire (https://tomcrane.github.io/fire/) are clearly not - the scene is composed, deliberately in a certain order and certain time.

Clients could still offer the user control over the visibility of elements, but the simplest and default case would be not to do this - it would be to render the scene as is.

For spatial content this means rendering the scene as described.
For this the Châteauroux example is useful:

In its source manifest this is not a Choice:

https://iiif.biblissima.fr/chateauroux/B360446201_MS0005/manifest.json
(search for "0038" for the first Canvas with an illumination)

While the specialist Châteauroux demo (https://demos.biblissima.fr/chateauroux/osd-demo/) gives users the ability to control visibility of the illuminations, by default a general client should render both images from the off.

There is no difference between this and Fire in that respect.

I suggest a change to the title of this recipe:

Composition of one view from multiple image sources

...which is a bit clearer I think.
